Transmit/receive switching circuit

摘要

A transmit/receive switching circuit implementation reduces transmitting/receiving switching losses in a transceiver during different modes of operation. The implementation includes connecting a low noise amplifier and a power amplifier in accordance with a shunt configuration in the transceiver. The implementation also includes disabling the power amplifier to achieve a high impedance state by grounding an output stage bias and enabling the low noise amplifier and disabling one or more transistors connected to a path between the low noise amplifier and the power amplifier during a receive mode.
